DateTime::Infinite(3) User Contributed Perl DocumentationDateTime::Infinite(3)NAMEDateTime::Infinite - Infinite past and future DateTime objects
SYNOPSIS
my $future = DateTime::Infinite::Future->new;
my $past = DateTime::Infinite::Past->new;
DESCRIPTION
This module provides two DateTime.pm subclasses,
"DateTime::Infinite::Future" and "DateTime::Infinite::Past".
The objects are in the "floating" timezone, and this cannot be changed.
BUGS
There seem to be lots of problems when dealing with infinite numbers on
Win32. This may be a problem with this code, Perl, or Win32's IEEE
math implementation. Either way, the module may not be well-behaved on
Win32 operating systems.
METHODS
The only constructor for these two classes is the "new()" method, as
shown in the SYNOPSIS. This method takes no parameters.
All "get" methods in this module simply return infinity, positive or
negative. If the method is expected to return a string, it return the
string representation of positive or negative infinity used by your
system. For example, on my system calling "year()" returns a number
which when printed appears either "inf" or "-inf".
The object is not mutable, so the "set()", "set_time_zone()", and
"truncate()" methods are all do-nothing methods that simply return the
object they are called with.
Obviously, the "is_finite()" method returns false and the
"is_infinite()" method returns true.
